Is there something like maximum activities in android app?I would like to know because I am thinking to create sound app with ringtone feature. It will have roughly around 40 activities. But only 1 will be running constantly.Is that too much? Should I find another way?
说明为什么我需要40个活动我有30种声音，我想将它们设置为铃声.1个正常活动，带有播放Mp和素材的按钮，以及35个其他活动，每个文件1个.我想要的是使用布局进行长按开始活动，并且会有更多按钮我尝试了上下文菜单，但效果不好.

推荐答案
由于活动数量众多，您不应该直接遇到问题，但是我对您的设计提出了疑问.可能很难正确设置并遭受性能问题，并且APK可能非常大.
You shouldn't have a problem directly due to the number of activities, but I question your design. It will likely be difficult to get right and suffer performance issues and the APK will probably be very overly large.
另一种方法可以利用以下事实:您可以针对单个活动有选择地使用/显示不同的布局，并且单个布局可以有选择地显示同一可见空间中的不同组件.
An alternative approach could utilize the fact that you can selectively use/show different layouts for a single activity and that a single layout can selectively show different components in the the same visible space.
